White blood cells help your body fight infections. Platelets help your blood to clot. Blood cell disorders impair the formation and function of one or more of these types of blood cells.
Thyroxine is a hormone made in the thyroid gland for the regulation of metabolism, body heat production, blood pressure, and the normal development of the skeletal and nervous systems. Thyroxine is an amino acid-based hormone that targets the genes involved in the metabolism of glucose in the body. Iodine in the blood is a key component of making thyroxine, and if not enough iodine is present, it can lead to the development of abnormal growths called goiters.
gland regulates metabolism in humans and other vertebrates. But in frogs, thyroxine has additional effects: it triggers the metamorphosis of a tadpole into an adult, stimulating resorption of the tadpoleâs tail and other changes.
